Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed September 21, 1904. Serial No. 225,387.

To all whom, 11/; may concern:

Be it known that I, SAMUEL F. FIELD, a citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented a new and useful Oill/Vell Pumping-Rig, of which the following is a specification.

This invention relates to a pumping power, and more especially to rigs of that general class wherein a number of oil-pumps are connected to a single power-transmitting means.

The principal. object of the invention. .is to provide a device of this class in which the apparatus is made for adjusting the connections to suit the locations oi" the pumps, the parts being so constructed as to permit of very many adjustments in accordance with the position of the pump, its stroke, the length of the connecting-rod, and the vertical height of the red.

A further object of the invention is to provide a device of this character in which the adjustments may be accomplished both quickly and accurately without the exercise of any special. mechanical skill.

With these and other obj eets in. view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement ol' parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure l is a plan view oi a pumping power constructed in accordance with the invention. Fig. 2 is a transverse sectional elevation oi the same on the line 2 2 ol" Fig. i. Fig. 3 a plan view of the base-plate. Fig. t is a detail perspective view of one oi the adj ustablc wrist-pin-carrying blocks detached. Fig. 5 is a similar view of another to rm of wrist-pin carrying block that may be employed.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures ol the drawings.

The device forming the subject oi" the present invention is one of that general. type employed in oil-regions for the sinndtaneous pumping oi a number of wells which. may be located at irregular distances from each. other and where the expense of separate pumping-engines and operating mechanism for each. well would be prohibitive. This mechanism designed as an intermediary between the engine or a similar source 6r power and. the several pumps.

The base-plate i0 is provided on its under face with a mnnber oi projecting lugs or ribs 2, which serve to more lirmly connect the bed-plate to its foundation or supporting timber. At the center of the bedsplate is a short vertical post 12, the outer surface ol which is faced and a'llords a bearing for the crank-disk 1.3. This base is further supported by an annular flange lel, which engages with the periphery of the disk-hu I). Tluitfpoirtion of the surlace ol the bed-plate between the periphery oi the post 12 and the inner wall of the flange .is provided with a number of drainage-open igs 15, through which any water or accumulations of lubricating material may Hadily pass. The crank-disk is held from vertical movement by a cap-plate l6 and bolt 17, the plate being oi a diameter suilicient to extend over the .hub oi" the crankdisk. The crank-disk is provided with an annular row ol. openings 17, around each of which. is grouped a series ol l. olt-recciving openings 18 and a series oi lugs 19, all oi the openings being ol the same size and all l eing cquidistantly spaced. From the edge of the crank-disk projects an ear or lug 21., to which. is connected. a rod 22, leading from an. engine or other source of power, and from this engine the eranledislc receives oscillatory movement to be transmitted through one or more colmeeting-rials to the \\'(;ll1.)Ul11})S or other points where the power is to be utilized.

in connection with. the cra11k-disk there is employed any desirable number 01' wristpincarrying blocks, and said blocks maybe of the construction shown in Fig. 1 or that shown in. Fig. 5. The block 25 shown in Fig. l: has a substantially circular body portion, in the bottom ol which are formed recesses 26 for the reception of lugs 19, and through said body portion. extend bolt-holcs 2-7, which may be in alinement with the bolt-openings 18 in. the UI:L]]l -(llSl(, and when once adjusted bolts are passed through these openings and firmly secured in place. As all of thdopen hugs and all oi the lugs are equidistantly spaced, the block maybe placed at any point on the cranlcdisk, and it may be turned with any one of the openings 17 as a center and.

adjusted to eight difierent positions with respect to each group of lugs 19. The block is provided with a projecting arm 28, carrying a number of wrist-pins 29 to any one of which may be connected the pump-operating rod, and by proper adjustment of the block connecting-rods of variable length may be employed and the power transmitted in any direction. In many cases the connecting-rods require wrist-pins disposed in a horizontal plane somewhat below that of the block 25, and in such cases blocks of the construction shown in Fig. 4 are employed. These blocks are provided with arms 28, the outer ends of which are in substantially the same plane as the upper surface of the crank-disk. The arm in this case is provided with a number of wrist-pins 29, to any one of which the rod or rods may be connected.

It is obvious that by employing the proper number of wrist-pin-carrying blocks the apparatus may be used for the transmission of power to a large number of pumps or employed for the transmission of power to aparatus of the same or different character. The connecting-rods may be led up to the crank-disk and the blocks attached to the disk in such manner as to properly accom modate the ends of the rods, and by further adjustment of the blocks the wrist-pins may be moved to a greater or less distance from the center of movement of the disk, and thus alter the extent of reciprocatory movement imparted to the rods.

Having thus described the invention, what is claimed is- 1. In an oil-well pumping-rig for the transmission of power from a central source to a plurality of pumps, a crank-disk mounted for oscillatory movement in a horizontal plane, and having an annular series of pin-receiving openings, a set of lugs and a set of bolt-receiving openings grouped around each opening, a wristpin-carrying block having a rigid centrally-disposed pin adapted to enter one of the pin-receiving openings and forming an axis for circumferential adjustment of the block, said block being further provided with recesses for the reception of the lugs, and with a set of bolt-receiving openings grouped around the pin in the same relative order as the bolt-receiving openings of the disk are grouped around the pin-receiving openings thereof, whereby said block may be adjusted circumferentially around the disk and around its own pin, substantially as specified.

2. In an oil-well pumpingrig for the transmission of power from a central source to a plurality of pumps, a crank-disk having an annular series of pin-receiving openings, a set of lugs grouped around each opening, the lugs of each set being correspondingly disposed throughout the entire series of sets, said crank-disk being further provided with a plurality of equidistantly-spaced bolt-receiving openings grouped around each pin-receiving opening, a wrist-pin-carrying block having a central pin adapted to any one of the pin-receiving openings, and being provided with recesses for the reception of the lugs, said recesses being equidistantly spaced to permit circumferential adjustment of the block, and bolts for securing the block in adjusted position.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

his SAMUEL F. FIELD.
